Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

To transform a UI object in 3-D space, create a custom IXRMatrix3D object, create an IXRMatrix3DProjection object, and pass the IXRMatrix3D object into IXRMatrix3DProjection::SetProjectionMatrix. Then, transform the UI object by passing the IXRMatrix3DProjection object into its inherited method IXRUIElement::SetProjection.

To define a custom 3-D transformation, specify a multiplier value for members of the 3-D matrix, such as M1 and M2, by using the Set methods. For information about setting these values, see Matrices on MSDN.

Or, you can define the 3-D matrix by using the methods on IXRPlaneProjection. After you do this, you can obtain the resulting IXRMatrix3D object by calling its method IXRPlaneProjection::GetProjectionMatrix.

When you create a class instance, use an IXRMatrix3DPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can also define a 3-D matrix in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about defining this attribute in the source XAML for your application, see Matrix3D Structure on MSDN.
